Abstract. A 100 hour (h) engine experiment was conducted to investigate the impact of post-injection strategy on emissions, combustion and lubricant dilution with a common-rail turbocharged direct-injection diesel engine at moderate speed and low load. The fuel was a B20 v/v blend of a soybean methyl ester-based biodiesel and ultra low sulfur diesel. The impacts of post-injection on engine per…
